In studies that have two tests (T1 T2) and one reference (R1) If I treated them in statistical analysis as on part ---> it called " William's design" But if I treated them in statistical analysis as two parts (T1 vs R and T2 vs R) ---> it called "Latin square design" IS THIS RIGHT? |

Hi Bebac user, ❝ In studies that have two tests (T1 T2) and one reference (R1) ❝ ❝ If I treated them in statistical analysis as on part ---> it called " William's design" Depends. If the designs had six sequences (T1T2R|T1RT2|T2T1R|T2RT1|RT1T2|RT2T1), it was a Williams’ design. If it had three sequences (T1T2R|T2RT1|RT1T2), it was a Latin Square. ❝ But if I treated them in statistical analysis as two parts ❝ (T1 vs R and T2 vs R) ---> it called "Latin square design" ❝ ❝ IS THIS RIGHT? No. Design ≠ evaluation. You can evaluate a Williams’ design either by a pooled ANOVA (that’s the ‘All-at-Once’ approach) or as two incomplete block designs (that’s the ‘Two-at-a-Time’ approach). See this article. — Dif-tor heh smusma 🖖🏼 Довге життя Україна! ![[image]](https://static.bebac.at/pics/Blue_and_yellow_ribbon_UA.png) Helmut Schütz ![[image]](https://static.bebac.at/img/CC by.png) The quality of responses received is directly proportional to the quality of the question asked. 🚮 Science Quotes |
